High durable, low-e, heat treatable layer coating system
View Patent ↗A coated article including a coating supported by a glass substrate is provided. In certain example embodiments, the coating includes from the glass substrate outwardly a first dielectric layer(s), an infrared (IR) reflecting layer (e.g., Ag), NiCrO X layer, at least one dielectric layer including silicon nitride and/or tin oxide, another IR reflecting layer (e.g., Ag), and at least another dielectric layer including silicon nitride and/or tin oxide.
1. A coated article including a coating supported by a glass substrate, the coating comprising from the glass substrate outwardly:
a first dielectric layer comprising tin oxide;
a layer comprising titanium oxide;
a first layer comprising Ag;
a first layer comprising an oxide of NiCr provided over and contacting the layer comprising Ag;
another layer comprising a tin oxide;
a layer comprising silicon nitride;
a layer comprising tin oxide;
another layer comprising titanium oxide;
a second layer comprising Ag provided over and contacting the another layer comprising the titanium oxide;
a second layer comprising an oxide of NiCr provided over and contacting the second layer comprising Ag;
a layer comprising a tin oxide; and
a layer comprising silicon nitride.
2. The coated article of claim 1 , wherein the coated article comprises a vehicle windshield.
3. The coated article of claim 1 , wherein the coated article has a haze value of less than 0.4, in accordance with ASTM D1003-61.
4. A heat treated coated article including a coating supported by a glass substrate, the coating comprising from the glass substrate outwardly:
a first layer comprising tin oxide and a second layer comprising an oxide of titanium;
a first layer comprising Ag;
a first layer comprising an oxide of NiCr provided over and contacting the layer comprising Ag;
a layer comprising tin oxide, wherein no metallic layer or metallic layer portion is provided between the first layer comprising the oxide of NiCr and the layer comprising tin oxide;
a layer comprising titanium oxide;
a second layer comprising Ag provided over the layer comprising titanium oxide;
a second layer comprising an oxide of NiCr provided over and contacting the second layer comprising Ag;
a layer comprising tin oxide provided over and contacting the second layer comprising an oxide of NiCr;
a layer comprising silicon nitride provided over and contacting the layer comprising tin oxide that is provided over and contacting the second layer comprising an oxide of NiCr; and
wherein the coated article has a visible transmission of greater than 70%.
5. The coated article of claim 4 , wherein the coated article has a haze value of less than 0.4, in accordance with ASTM D1003-61.
6. The coated article of claim 1 , wherein the coated article is heat treated.
7. The coated article of claim 1 , wherein the coated article is heat treated and has a visible transmission of greater than 70%.
